摘要
纳米氢氧化镁因其绿色、高效等优势在塑料、橡胶等高分子材料的阻燃方面有广泛的应用前景.随着研究的深入,沉淀法、水热/溶剂热法和微波辅助法等制备方法已在纳米氢氧化镁的制备中占据主导.本文首先从纳米氢氧化镁形貌与粒径的控制方面介绍了这3种主流制备方法,对部分制备过程中的作用机理进行了探究,对每种制备方法的优劣进行了阐述,进而对制备方法进行对比总结.其次讨论了纳米氢氧化镁在应用领域存在的问题及解决办法,概述了其在多种高分子材料阻燃领域的应用,并以理论结合实例从多个角度探究了纳米氢氧化镁的阻燃机理.最后对目前纳米氢氧化镁制备方法和应用方面遇到的机遇和挑战进行了展望,希望能为纳米氢氧化镁的进一步深入研究提供有益的启发和参考.
Abstract
Nano magnesium hydroxide has a wide application prospect in the flame retardant of polymer materials such as plastics and rubber due to its advantages of green and high efficiency.With the deepening of research,preparation methods such as precipitation method,hydrothermal/solvothermal method and microwave-assisted method have dominated the preparation of nano magnesium hydroxide.In this paper,these three mainstream preparation methods were introduced from the aspects of morphology and particle size control of nano magnesium hydroxide.The mechanism of action in some preparation processes was explored.The advantages and disadvantages of each preparation method were described,and then the preparation methods were compared and summarized.Secondly,the problems and solutions of nano magnesium hydroxide in the application field were discussed,and its application in the field of flame retardant of various polymer materials was summarized.The flame retardant mechanism of nano magnesium hydroxide was explored from many angles by combining theory with examples.Finally,the opportunities and challenges encountered in the preparation methods and applications of nano magnesium hydroxide were prospected,hoping to provide useful inspiration and reference for further research on nano magnesium hydroxide.
